Plasma cutting is used in cutting and gouging applications, and requires compressed air and electricity to create plasma gas. Miller plasma cutters can cut up to 7/8-inch steel and stainless steel material, and up to 5/8-inch aluminum material.
Does Miller make a plasma cutter with a built in compressor?
VanGrinsven says his shop and field welders increased productivity when they switched from power saws and electric cutters to a Spectrum® Thunder plasma cutter with built-in air compressor from Miller Electric Mfg. Co. "We've increased production and labor 25 percent using the Spectrum Thunder plasma cutter.Mar 1, 2007
Regarding initial investment cost to purchase a machine, the lowest cost would be a plasma cutter. Depending on type, size, and features, a CNC plasma cutting machine could range anywhere from $15,000 to $300,000.
Do plasma cutters require an air compressor?
But if you do a lot of cutting, or plan to cut thick plate, we recommend using a compressor that is 1.5 to 2 times the plasma system requirement. Beyond choosing the right size air compressor for your plasma cutter, it is critical that you ensure the air that reaches your plasma cutter is high quality air.
Why does a plasma cutter need compressed air?
You must select a suitable air compressor to be able to supply the correct amount of air flow to your plasma cutter. Using too small an air compressor will result in the air compressor running all the time, and also the lack of correct air pressure to the plasma cutter will result in a poor consistent cut.
Do Plasma cutters use air?
Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen. ... This high speed gas cuts through the molten metal. The gas is also directed around the perimeter of the cutting area to shield the cut.
How much air does a plasma cutter need?
The minimum flow/pressure requirements of the plasma cutter you intend to use. The manufacturer can provide the specs and they can vary from model to model. A small Hypertherm Powermax30 will use about 4.5 cfm (cubic feet per minute) at 90 psi inlet pressure. A Hypertherm Powermax45 uses 6 cfm at 90 psi.Sep 5, 2013
What is the output voltage of a plasma cutter?
The plasma jet immediately reaches temperatures up to 22000° C, quickly piercing through the work piece and blowing away the molten material. Power supply -- The plasma power supply converts single or three phase AC line voltage into a smooth, constant DC voltage ranging from 200 to 400VDC.
What are the input voltages for the plasma cutter?
90 psig Plasma cutter measures 8.75" X 18.5" X 13.5". It has an input voltage rating of 208 - 230 V and current rating of 44 - 47 A.
Do plasma cutters use AC or DC?
Power supply – A constant current DC power source. The open circuit voltage is typically in the range of 240 to 400 VDC. The output current (amperage) and overall kilowatt rating of the power supply determines the speed and cut thickness capability of the plasma cutter.
